TreeGraph

A mixin to help you generate tree graph.

Add this line to your application's Gemfile:

gem 'tree_graph'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tree_graph

In Node class, include TreeGraph, then implement two methods, label_for_tree_graph and children_for_tree_graph(which return thing responds to each). Then you can call tree_graph, tree_graph_bottom_up and tree_graph_bottom_up_in_same_order on that Node object.

By default, ::Object#label_for_tree_graph call to_s, and ::Object#children_for_tree_graph return empty array.

Or checkout test/tree_graph_test.rb to see how to use.

Gems depending on tree_graph: constree, trace_tree.
